Following that, Klein's gaze turned to the strengthening coupons in his hand.

[Weapon strengthening coupons can be placed on the weapons that need to be strengthened. It can raise the weapon to the level marked on the strengthening coupon. The the higher the success rate of the strengthening coupons, the higher the success rate of the strengthening.]

Looking at the system notification, Klein couldn't help but laugh.

He now had a total of three strengthening coupons.

One +7 had a 100% success rate.

One +8 had a 30% success rate.

And another +5 had a 100% success rate.

This was terrifying wealth.

One had to know that back then, Klein had spent more than 800 souls to increase the success rate of the +8 Endless Sword. That kind of heartache was simply inhumane!

Thankfully, Klein was wealthy. If it were anyone else, they would probably be heartbroken if they had such a large number of souls, much less possess them!

He didn't expect the strengthening coupons to drop.

This made Klein's eyes light up.

Putting everything else aside, just these few strengthening coupons would probably be worth at least 200 souls.

+7 strengthening coupons would at least be worth at least 500 souls.

Of course, the +8 strengthening coupons were also very powerful. If he were to find a greedy gambler, he might be able to sell a soul that was even higher than +7!

...

Just as Klein put away all the treasures, the full service announcement sounded once again.

[Congratulations to the strongest expert in the catacombs world, Klein, for opening the Platinum Treasure Chest.]

The full service announcement slowly scrolled through everyone's interface.

At that moment, everyone couldn't help but notice the news.

"Platinum treasure chest?" Someone spoke, but the words were filled with doubt and disbelief.

"What is this thing? Has anyone seen it before?" someone asked.

Before this, the highest-grade treasure chest in the catacombs world was a golden treasure chest.

And the appearance of the platinum treasure chest clearly let them know that the golden treasure chest was not the highest grade treasure chest.

But the golden treasure chest was originally very rare in the catacombs.

No matter who encountered it, it was an unprecedented bumper harvest, not to mention the platinum treasure chest. Everyone was shocked by the world's news.

"I thought the golden treasure chest was the most awesome, but I didn't expect there to be a platinum treasure chest on it. Oh my god, what can drop from it? Perfect weapon? Epic weapon? Or legendary weapon?"

"Don't, don't, don't say that. My heart can't take it anymore."

"Sigh, I'd better forget about it as soon as possible. This thing can wake me up even in my dreams. I can't help it, it's just a legendary item."

"Indeed, I've never seen a golden treasure chest in my life."

"Pfft, a golden treasure chest? I've never even seen a silver treasure chest before. You guys better be good people. Don't provoke me!"

"I won't hide it from everyone. I once obtained a golden treasure chest. That time, I obtained a powerful perfect weapon as well as other good items. This allowed me to directly rise from the bottom to the top of the rankings. Therefore, I can guarantee that the lowest inside the platinum treasure chest is an epic weapon, and its rank isn't low either!"

"Of course, it must be an epic weapon. Oh my god! Whoever gives me one, I'm willing to sell my soul."

"Similarly, I don't even have a perfect weapon now. An epic weapon? I guess I can only dream about it!"

...

"Sigh. It's Lord Klein again? I didn't expect the difference in strength between us and Lord Klein to be so great. Does anyone know what level Lord Klein is at?"

"Heh heh, what level? In any case, it's right that you can't imagine it. Unless you can beat that huge rock that once blotted out the sky, you have no way of gauging the strength of God Klein!"

"I heard that the more powerful a treasure chest is, the stronger the crypt creatures in it are. And since Klein has obtained the first platinum treasure chest in the catacombs, the crypt creatures he's facing are definitely on a terrifying level!"

"Terrifying? Are you looking down on God Klein?"

"That's right, what's this? No matter how powerful he is, how can he be as powerful as that rock golem?"

"There's no doubt that he's the strongest existence in the catacombs world is God Klein!"

"God Klein, come out and explain what's going on with the platinum treasure chest!"

"Ditto, +1, +1, +1!"

...

Klein couldn't help but shake his head as he watched the full service announcement flash by.

He didn't expect the platinum treasure chest to have really appeared for the first time.

It seemed like he had invisibly gained a sense of presence in front of everyone in the catacombs world!

However, the drop rate of the platinum treasure chest was indeed quite good.

Not to mention the epic weapons that dropped, even the souls and runes were worth the ticket price.

Especially the last three strengthening coupons.

If they were to be released, it would probably shock everyone, right?

One had to know that back then, Klein had spent more than 800 souls to strengthen the +8 Endless Sword.

This was an astronomical figure for everyone, including Klein.

Now that there was a shortcut, naturally, everyone couldn't help but be excited.

Furthermore, even if there were 800 souls, there was no guarantee that they could be strengthened to +8. This was a matter of probability, which was also the legendary matter of looks.

Ugliness is thicker than self-awareness.

But strengthening coupons were divine coupons that could be directly strengthened successfully.

Compared to the uncertainty of strengthening, strengthening coupons clearly gave everyone a certain future. Therefore, the value of the two couldn't be compared in everyone's hearts.

...

In the cave that Klein had experienced previously, which was the cave that faced the undead Giant and the mysterious man, there was suddenly a loud bang.

Soon, the sound grew louder and louder. Finally, with a whoosh, the catacomb was opened.

After it was opened, a few people walked out.

These people were all covered in sweat and looked exhausted. As soon as they entered the cave, they couldn't help but sit on the ground.

Suddenly, the leader said, "What are you doing? This is a new cave. Quickly check the surroundings. Be careful of any crypt creatures!"

"Hey, boss, I'm so tired. In order to escape that destructive wave, we have been digging several caves consecutively. Let us rest for even a minute."

"Hey, I know everyone has worked hard, but now is not the time to rest. Once the crypt creatures attack, I'm afraid it's a question of whether everyone can survive. You have to know that the monsters in this cave are several times stronger than the monsters in other places!"

"Alright!"

Hearing their boss's words, the few of them stood up unwillingly and forced themselves to look around.

However, the world in front of them was very quiet.

From afar, the endless forest looked like an ocean of forest. Everyone who was looking at it could not help but let out a sigh of relief.

Just as most of them were enjoying the scenery in front of them, a sudden exclamation was heard.
